Years ago, a wireless was a radio. Now, having a wireless doesn’t mean you sit around listening to a box and trying to imagine pictures. It means wireless internet.

Wireless broadband works by using short-range radio waves to create a small area where your computers can be networked without wires - most wireless networks are no bigger than a house, although larger ones are possible.

This is how it works. First, the broadband Internet connection is plugged into a wireless router - basically, a small, cheap computer that does nothing except acting as the hub of your network. You then fit wireless cards into each one of your computers, either by opening them up and putting it inside or by plugging it in using a cable (such as USB) or a port (like laptops’ PCMCIA).

When you fit these cards and turn your computer (and the router) on, Windows should pop up a box asking you which wireless network you want to connect to. Your router should create a network automatically, generally naming it after its manufacturer (’netgear’ or ‘linksys’, for example). All you need to do is choose this network, and you’re on the Internet.

Wireless broadband can be either paid for monthly along with your standard tariff, or used on a pay-as-you-go basis for periods of up to an hour. It all depends on how much you travel, and how often you would use the service. Wireless broadband and wireless networking are slowly becoming more widely available as more providers catch onto the idea.
